...e that this is out there," she said. "When someone comes in, doctors should be aware that this could be a muscle abscess." Antibiotics that successfully treat MRSA include oral clindamycin and trimethoprim-sulfamethoxazole, which are usually used out of the hospital, and vancomycin or clindamycin, which ...

Obesity levels in US are grossly underestimated

...derestimate their weight while men do not. When it comes to height, young and middle-aged men tend to overestimate their height more than women in the same age group. In 2002, the corrected prevalence of obesity in the U.S. population was 28.7% for adult men and 34.5% for adult women, more than 50% higher ...

Biotech cotton provides same yield with fewer pesticides

...Bt cotton, according to new research. The finding comes from the first large-scale study that simultaneously examined how growing Bt cotton affects yield, pesticide use and biodiversity. It's good news for the environment. "What we see is that it's positive here in Arizona -- no doubt about it," said Yve...

Beauty and the brain

...eas that explanation makes intuitive sense when it comes to human faces, Winkielman said, it strains credulity when applied to inanimate objects or animals of a different species, which we are presumably not assessing for reproductive purposes. So Winkielman, with colleagues from the University of Otago...

...system, and we don't understand how this diversity comes about," Goulding explains. Referring to the multiple roles of Notch, not only in controlling the differentiation of neurons but in determining their excitatory/inhibitory activity, he adds: "Given that we now have a detailed description of how Notc...

Bacterial 'switch gene' regulates how oceans emit sulfur into atmosphere

...al Science. Much of the sulfur in the atmosphere comes from the surface of oceans, from a compound called dimethlysulfide, or DMS. Marine plankton control how much sulfur rises into the atmosphere by converting a compound called DMSP, or dimethylsulfoniopropionate, to DMS or to sulfur compounds that are ...

Researchers find that bumblebees' flower choice matters

...y flower mating, and all hinge on where the pollen comes from. Pollen allows the flowers, which contain both male and female reproductive organs, to produce seeds. Plants can only produce seeds from their own species' pollen. The pollen from another species deposited on a monkey flower, for example, is ...

Approximately 30 of the animals currently live there, down from a high of nearly 600 estimated in 1940. The authors caution that additional reductions in the population could harm...

Evolution reveals an independent route for diversity in animal form

...he spectacular morphological diversity in Cnidaria comes as a surprise. The Cnidaria is one of the most diverse and species-rich of animal groups, ranging in shape and size from microscopic solitary polyps to massive and highly differentiated colonial siphonophores up to 40 meters long.

Fire ants: Their true story told by the scientist who loves them

When it comes to fire ants, most people prefer to wipe the venomous little varmints off the face of the Earth ?or at least out of their own back yards. The reviled South American native that invaded the U.S. Sun Belt via 1940s Mobile, Ala., is known in biology cir...

Such stress comes from the same chemical process that makes cars rust in the Rochester winter: Free-wheeling molecules known as free radicals zing through materials and run roughshod over anything in their way, including vital proteins and DNA. It's a major reason why...

"But in our case, because our sponge and the channels within it are essentially nanoscopic, the water cannot get out, at least not fast enough to allow for a reorganization of the material, and therefore it just rigidifies th...

New research finds surveys of larval-stage organisms effective for measuring marine biodiversity

...is challenge is not well known, especially when it comes to vast and often inaccessible marine environments. To date, surveys of species diversity in the world's oceans have focused on adult organisms, but new research from Boston University has found that studying marine life in its larval phase with DNA ...

Biofuels researcher searches for new sources

...er 90 percent of ethanol made in the United States comes from corn grain. However, other sources of ethanol are needed, because even if the entire United States' corn crop was used for ethanol, it would meet only 10 percent of the country's fuel needs. So researchers are looking for new sources for ethan...
